[Fedora-legal-list] clarifying license of rubygem-posix-spawn

[Ken Dreyer]

Hi folks,

I'm trying to sort out the license tag for rubygem-posix-spawn. This
package has a function that's copied from glibc. As explained in the
footnote (https://github.com/rtomayko/posix-spawn/blob/master/COPYING#L24-L28)

  A small portion of the environ dup'ing code in ext/posix-spawn.c
  was taken from glibc <http://www.gnu.org/s/libc/> and is maybe
  Copyright (c) 2011 by The Free Software Foundation or maybe
  by others mentioned in the glibc LICENSES file. glibc is
  distributed under the terms of the LGPL license.

>From what I understand, this makes rubygem-posix-spawn dual-licensed
under the MIT and LGPL licenses, right?

I've opened a ticket upstream, and I'm not sure how to respond to
https://github.com/rtomayko/posix-spawn/pull/44 the author's comment
about the block glibc code being de minimis.

To summarize, should rubygem-posix-spawn have a License tag of "MIT
and LGPL", or just "MIT" ?
